<P class=MsoNormal><SPAN
style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'">We
also have not mentioned another item relative to Appendix G, which requires
sizing the flow rate based on a 20-degree delta T. If the system is a 100% OSA
unit, and the baseline is sized for a 20-degree space-to-coil temperature
differential, what happens if the makeup air unit is not designed with a
20-degree delta-T? Then it is possible the peak CFM rates could potentially
vary. So right there, we could potentially have a contradiction between 2 lines
in Appendix G – (1) OSA ventilation rates are to be identical, and (2) The
baseline AHU flow rate is specified by a 20-degree delta T – now, which
statement in Appendix G “over rules” the other?<o:p></o:p></SPAN></P>

regarding an earlier item from this thread, that one cannot take credit for UFAD
and displacement ventilation systems with reduced CFM rates – as long as the OSA
CFM rates are identical, then credit can be taken from the UFAD/DV system
design. You’ll be providing the same OSA, but different Total CFM rates could be
calculated based on the different mixed air temperatures and designed coil
leaving temperatures. This can be either a positive or negative, which truly
depends on the climate and the ability to maximize the economizer
hours…<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN

a fascinating convergence of issues. </SPAN><o:p></o:p></P>
<P class=MsoNormal> <o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">Appendix
G's requirement for the same minimum ventilation rate in the baseline
as the proposed is true but also a bit incomplete when considering a
design of a 100% OA VAV systems serving fume hoods.</SPAN><o:p></o:p></P>
<P class=MsoNormal> <o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">We have
a similar scenario of a small building with likely VAV hoods, possibly lower
flow, likely served by a 100% outside air system BUT with my
favorite added complexity of district heating and cooling.

<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">So I
have not fully solved it for myself and cannot solve for it your
project but I do suggest the following
actions:</SPAN><o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">1) Read
the 90.1-2004 prescriptive requirements for certain systems serving fume
hoods to be VAV or have heat recovery. </SPAN><o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">2) Read
the 90.1-2004 Appendix G base system selection
section</SPAN><o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">3) Now
read those same sections in 90.1-2007 and ponder which
changes represent revisions and which ones represent clarifications of original
intent</SPAN><o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">4) And
maybe read the User's Manuals too</SPAN><o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">5)
Consider the exceptional calculation method as the venue to claim
energy savings, that you consider real but
are not explicitly allowed or defined by the document,
for consideration by the LEED reviewer</SPAN><o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">6) Research
the existing CIR's</SPAN><o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">7)
Before spending numerous hours on an approach that may or may not be
accepted, buy a CIR and propose your tact to the USGBC itself. If
they reject yours they almost certainly will dictate a new
tact that their reviewer would be obligated to accept for your
project.</SPAN><o:p></o:p></P>
<P class=MsoNormal> <o:p></o:p></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Arial','sans-serif'">And
lastly, do not wade too much further through this on a Friday afternoon unless
you have to do so. For me, tasks like this should be tackled early in the day
and early in the week.</SPAN><o:p></o:p></P>

<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'">The
mechanical engineer for a campus laboratory building with 100% OA wants to
claim energy savings for reduced exhaust from more efficient fume hoods.
(Established design practice uses hoods with 100 fpm flow – they are
installing 70 fpm hoods. This reduces peak exhaust from 700 to 490 CFM per
hood.) My approach has always been to keep outside air, exhaust and
infiltration flows identical between the proposed and baseline models (except
for DCV). (This was not easy for this model with proposed VAV and baseline
constant volume packaged rooftops.)</SPAN><o:p></o:p></P>
